Patent CA-2184371-A1 (CA)
Title: Switch-over arrangement for load switches of tap changers and for load selectors
Inventor: PILLMEIER LEONHARD
IPC: H01H9/00
Filed: 1995-03-08
Abstract: The invention concerns a switching arrangement for load change-over switches of step switches and for selector switches, wherein two switching contacts movable in two directions are present. The first switching contact is in the form of a main switching contact and is connected to the load derivation by means of a first vacuum switchgear cell.  The second switching contact is in the form of a resistance switching contact which is likewise connected to the load derivation by means of a series connection comprising a second vacuum switchgear cell and a transition resistor. Both the main and the resistance switching contacts can be moved independently of one another and without mutual coupling or influence. The main switching contact always reaches the new fixed contact abruptly and independently of the switching direction before the resistance switching contact leaves the previous fixed contact.

Title: Apparatus and method for flushing transmission fluid
Inventor: BEHRING MELVIN A
IPC: F01M11/04
Filed: 1995-03-06
Abstract: An apparatus (10) is disclosed for completely flushing transmission fluid from a transmission in a vehicle (12). The apparatus includes a storage tank (18) which is connected to a cooler line (38, 40) extending between the transmission and a transmission cooler (radiator) so that the vehicle transmission pumps the used transmission fluid directly into the storage tank. Simultaneously, replacement fluid is supplied from a supply tank (20) and pumped into the dipstick tube (32) of the transmission by a suitable pump (22). In this manner, the used fluid is quickly and completely flushed from the transmission.

Title: A system and method for representing and retrieving knowledge in an adaptive cognitive network
Inventor: MOLLOY BRUCE G
IPC: G06F17/30
Filed: 1995-06-21
Abstract: An adaptive learning system in which knowledge is represented in the form of discrete concepts that are associated with one another.   Each such association of concepts is called a case. In accordance with the invention, the degree of association of the concepts in the various cases can be specified by a mathematical score. As a result, if one concept such as the description of a problem is specified to this system, the system will identify associated concepts such as the likely solutions of the problem in the order of likelihood. The adaptive learning system is initialized by loading into the system cases which typically were derived from previous experience. The cases are stored by the processor in a case table in long-term memory (Case Library). Each of the concepts identified in the cases is stored in the concept table in the long-teem memory (Concept Library). From these cases the processor can generate in real time ordered lists of concepts (Cognitive Processor) which are most closely associated with free text or with one or more concepts that are provided as inputs to the system (User Interface).

Title: Process for obtaining 2-hydroxy-4-methyl thiobutyric acid (mha), mha and its use
Inventor: HASSEBERG HANS-ALBRECHT
IPC: A23K1/16
Filed: 1995-06-28
Abstract: It is known to isolate MHA from a reaction mixture obtained by the addition of hydrocyanic acid (HCN) to methyl mercaptopropionic aldehyde (MMP) and the hydrolysis of the methyl mercapto propionic aldehyde cyanohydrine (MMP-CH) obtained thereby with sulphuric acid, in which the reaction mixture is brought into contact with a substantially non-water-miscible organic solvent, in order to form an extraction solution having the solvent and MHA transferred from the reaction mixture, and the MHA is obtained as an extract from this extraction solution by concentration. The simplest and most economical process of the invention concerning the processing of the reaction product which facilitates the production of a highly concentrated product with an extremely low dimer, oligomer and by-product content, is characterised in that the concentration is conducted in such a way that the remaining extract contains less than 4 wt %  and preferably less than 2 wt % of water.

Title: System for monitoring a dual voltage ungrounded system
Inventor: BENESH STEPHEN PATRICK
IPC: G01R31/02
Filed: 1995-08-17
Abstract: A system contained on a single isolation panel determines the hazard current of a dual voltage, ungrounded, polyphase system. The system uses a single isolation transformer having dual secondary windings for generating the dual voltages. A first line isolation monitor or LIM, is microcontroller based and continuously measures the fault impedance of one of the output voltages of the polyphase, ungrounded or isolated system. A second LIM continuously measures the fault impedance of the other output voltage of the system. The fault impedance is determined by the LIM by injecting a continuous sine wave measurement current into a ground terminal to generate a measurement voltage across the fault impedance. Using the measurement voltage and current, the LIM calculates the fault impedance and, using this impedance, calculates the hazard current based on the maximum line to ground voltage of the ungrounded system. The hazard current is displayed and if it exceeds a predetermined threshold, the LIM will provide audio and visual alarms. A serial communications channel allows the LIM to communicate with other intelligent devices. The LIM has means for self-calibration and self-testing while on-line and during a power-up sequence. Line frequency is also determined by the LIM. The two LIMs can be used to monitor the dual distribution system at the same time without interfering with each other.

Title: A stackable block system
Inventor: FREDERIKSEN JESPER BO
IPC: A63H33/08
Filed: 1995-09-28
Abstract: A stacking block system having stacking blocks which have a body part which is provided with coupling knobs with a mutual uniform modular distance on its upper side and is downwardly provided with coupling means which are complementary with respect to the coupling knobs on the upper side and are adapted to be coupled with the coupling knobs. According to the invention, the blocks are additionally provided with one or more spacers downwardly, which are designed such that when two stacking blocks are stacked on top of each other, the body parts of the stacking blocks will be spaced from each other along their entire periphery.      This provides a gripping edge or a gap between two blocks stacked on top of each other, so that it is particularly easy to grip the blocks when a stack of such blocks is to be separated.

Title: Mechanical system for blind nail-hole alignment of bone screws
Inventor: ROSSI STEFANO
IPC: A61B17/17
Filed: 1997-04-24
Abstract: An all-mechanical system for bone-drilling alignment of a blind distal bone-screw hole of an installed intramedullary nail, wherein the system provides (i) a drill jig that features a longitudinally adjustable nail-contactable contact-rod mounting in the jig and (ii) a drill-guide which can align with the blind distal bone-screw hole for a correct nail-contactable adjustment of the contact rod.  The system enables the surgeon to checkout the drill jig in assembled relation to a selected intramedullary nail, prior to nail installation, and to perform an adjustment to compensate for nail diameter when the contact end of the rod engages the nail.  He can then either visually satisfy himself of the drill-guide/bolt-hole alignment, or he can use a plug-gage or trocar tool having guidance in the drill guide, and checking for whether the plug gage has entry into the bone-screw hole in the intramedullary nail.  Having thus ascertained that the adjusted contact-rod position can correctly identify drill-guide alignment with one or more bone-screw holes of the intramedullary nail, it is only necessary, after installing the nail and connecting the jig to the proximal end of the nail, to make a small local surgical incision through flesh and bone sufficient to enable direct stabilizing (contact-rod) contact with the nail, whereupon it is known that the drill guides are in correctly drillable alignment with the targeted bone-screw holes of the installed nail.  Drilling and setting of bone screws can immediately proceed in customary manner.
